0025284: Problems with standard MFC samples

 - OCAF sample Save Document option: corrected conversion from LPCTSTR to Standard_CString
 - HLR sample: corrected mouse move event handling for HLR 2D view; Corrected CSelectionDialog view displaying and updating
 - Geometry sample: CGeometryDoc correction to avoid code duplication
 - OCC_3dBaseDoc: corrected DragEvent() handler for proper emulation of rectangle selection.
 - Viewer3d sample: moved resource files (resource.h; resource.hm; AISToolbar.bmp) from /src to /res

Code style changes

Fixed "About" dialog error in release.

Corrected dimension dialogs

Workaround for dimensions sample: AIS_LocalContext::SelectedShape() doesn't take into account TopoDS shape local transformation, and operates with selected interactive transformation.
